Harmony Rollback Target Set at Block 92.7M After 4B ONE Minted

Harmony halts cross-chain services and initiates rollback to block 92.7M after a Cross-Shard Receipt Replay bug caused 4 billion ONE minting in the first wave.

Woofun AI reports that Harmony identified a Cross-Shard Receipt Replay vulnerability as the root cause of recent minting anomalies, allowing valid receipts to be processed repeatedly without corresponding deductions. An emergency patch was deployed on August 12 to address the flaw. The network has suspended cross-chain operations and paused Shard 0 at block 92,753,555 to facilitate a state rollback to target block 92,730,034. Initial assessments confirm 4 billion ONE were minted in the first wave, with total falsely generated tokens across shards estimated at approximately 3.01 trillion, though figures remain under verification. The team is currently coordinating with validators and exchanges to finalize the recovery plan.
